  1. 1. Electrical Pulsing of a Laser Diode for Usage in Fluorescence Microscopy

    Master-uppsats, Linköpings universitet/Elektroniska Kretsar och System

    Författare :Karin Jerner; [2017]
    Nyckelord :electrical pulsing; laser pulsing; fluorescence microscope; laser diode;

    Sammanfattning : A relatively new application for the laser is in fluorescence microscopes. The fluo- rescence microscope needs a high power light source input. Using a laser source improves the precision of the microscope. A pulsed laser source enhances the performance of the fluorescence microscope and a laser diode can be overdriven without being damaged.

  3. 2. High Voltage Pulsed Power Converters for the ESS Linear Accelerator.

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Industriell elektroteknik och automation

    Författare :Tobias Ogard; Simon Persson; [2014]
    Nyckelord :Technology and Engineering;

    Sammanfattning : Material science has become an important research area in order to fulfill today’s requirements on lighter, cheaper and more sustainable materials. The European spallation source is a research center based on the world’s most powerful neutron source, which will enable new possibilities to evaluate material properties down to an atomic level.

  4. 3. Pressure Control of a Pneumatic Actuator Using On/O Solenoid Valves

    Uppsats för yrkesexamina på avancerad nivå, KTH/Reglerteknik

    Författare :Maisam Jeddi Tehrani; [2008]
    Nyckelord :;

    Sammanfattning : Nowadays a very important aspect in heavy duty vehicles is the braking system. The braking system can be divided into EBS brakes, exhaust brake and retarder, where the latter is of interest in the present Master's Thesis. This thesis presents an investigation whether it is possible to substitute today's concept, i.e. LÄS MER

  5. 4. Modeling and Control of Retarder using On/Off Solenoid Valves

    Uppsats för yrkesexamina på avancerad nivå, KTH/Reglerteknik

    Författare :Vidar Steinsland; [2008]
    Nyckelord :;

    Sammanfattning : The Retarder is one of the main components in Scania's trucks' braking system and is used to brake down the truck and for maintaining a steady speed on descents. This Master's Thesis aims to investigate if the current system which uses a proportional valve to control the air pressure in the Retarder, can be replaced with two on/o® solenoid valves and a pressure chamber to control the air pressure, which would result in a cheaper and more robust system.
